    PREPARATION FOR HV BATTERY CHARGING

    CAUTION:

    • The hybrid system has high-voltage circuits. Accidents, such as electric shock, or electric leaks may result if the hybrid system is not operated in a correct manner. Make sure to follow the correct procedure (Click here).

    • Wear insulated gloves.

    Tip:

    • Removing the service plug grip interrupts the high voltage circuit.

    • High voltage wiring connectors are orange.


    1. Check the charge level of the HV battery.


      1. A00042Z

        Check whether the HV battery warning message is shown in the multi-information display.

      2. Confirm if the engine starts. If the engine starts, leave it idling with the shift lever in P until the engine stops (self charge has completed).

        If the engine cannot start, follow the procedure and charge the HV battery.

        Tip:

        • Before performing external charging, always use the GTS to perform troubleshooting.

        • Charging time using the THS charger is 10 minutes per charge cycle. The charging time when using a THS charger is a short charging time (when the battery temperature is 25°C (77°F), 10 minutes may be sufficient, if the battery temperature is 0°C (32°F), then three 10 minute charge cycles may be required) for putting the engine in a condition where it can be started (the system can enter the READY-on state). (The THS charger will automatically stop 10 minutes after charging starts.)

    2. Remove the service plug grip (Click here).

    3. Remove the cool air intake duct seal (Click here).

    4. Remove the inlet air cleaner assembly (Click here).

    5. Remove the air cleaner cap sub-assembly (Click here).

    6. Remove the air cleaner filter element (Click here).

    7. Remove the air cleaner case sub-assembly (Click here).

    8. A0008X5

    10. A0006NU

      Remove the bolt from the inverter with converter assembly.

    11. A0005UK

      Disconnect the wire harness clamp and frame wire.

    12. A0006EX

      Measure the resistance according to the value(s) in the table below.

      Tip:

      If the shield line of the frame wire is not securely connected to body ground, the THS charger will not operate. The "FAULT" and "CABLE CONNECTION" warning lights will illuminate on the THS charger.

      Standard Resistance
      Tester Connection Condition Specified Condition
      Frame wire connector housing - Body ground Always Below 1 Ω
    13. A0009MM

      If the result is not as specified, inspect the connection shown in the illustration for proper installation (Click here).

      3 ON OFF → ON ON ON

    4. Make sure that the EMERGENCY STOP switch is in the reset condition (the switch is turned clockwise and released).

    5. Make sure that the BREAKER is in the ON position.

    6. A0003UG

      Turn the THS charger MAIN switch on.

      Tip:

      The MAIN indicator will illuminate green.

    7. A000413

      Press the START switch.

      Tip:

      • When the START switch is turned on, the INITIAL CHECK indicator illuminates and an initial check starts. When the initial check completes successfully, the INITIAL CHECK indicator turns off, the CHARGING indicator illuminates and charging will start at the same time.

      • While the INITIAL CHECK indicator is illuminated, the insulation, 400 V output, emergency stop switch, connector connections and ground connection are inspected.

    8. Repeat the charge cycle 3 times. When the last cycle has finished, turn the THS charger MAIN switch off.

      Tip:

      • Charging time using the THS charger is 10 minutes per charge cycle. The charging time when using a THS charger is a short charging time (when the battery temperature is 25°C (77°F), 10 minutes may be sufficient, if the battery temperature is 0°C (32°F), then three 10 minute charge cycles may be required) for putting the engine in a condition where it can be started (the system can enter the READY-on state). (The THS charger will automatically stop 10 minutes after charging starts.)

      • There is very little chance of overcharging the HV battery during the second or third charging cycle. The SOC will not likely increase beyond the upper limit because it was low enough to prevent the engine from starting. Even if the SOC was to increase enough to exceed the limit, the hybrid vehicle control ECU will stop the active test to prevent overcharging.

      • Cranking the engine once causes the SOC to drop approximately 1%.

      • Charging the HV battery once (10 minutes) using the THS charger restores the SOC approximately 2%.

    9. Turn the power switch off.

    10. Remove the THS charger and install the frame wire.

      Note:

      Make sure to disconnect the EV bonding cable last.


      1. Disconnect the power inlet plug of the charger from the grounded AC 100 to 240 V receptacle.
